A brother and I called at a house one afternoon.
The door was answer by a young guy (20ish), bare-chested, who hid rest of his body behind door.
I could here the brother behind me trying not to laugh.
I then glance down and saw they though the guy was hiding behind the door, it was glass fronted.
We could see he was completly naked.
Yet he still stayed there as I made my presentation.
So I delibrately streched it out, just waffling on.
After about 10 minutes a female voice came from upstairs.
"John , you coming back up here."
The guy went red.
So I said "Well I see you have other things to do. I'll just leave you these magazines."
The brother and I walked down path trying not to burst into laughter.
